EYEGLASSES.

Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed October 27, 1905. Serial No. 284,756.

To all whom it may concern.-

Be it known that I, LINOOLN L. STONE, a

' citizen of the United States, residing at Canton, in the county ofBradford and State of Pennsylvania, have invented certain new and usefulImprovements in Eyeglasses; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to eyeglasses; and the principal object of thesame is to provide means for the connection of the bridge-piece and thenose-piece to a stud-post without the use of screws or other extraneousmeans.

Another object is to provide a connection for the nose-pieces andbridge-piece which will permit the detachment of said parts from theframe of the glasses without the use of a tool and which will alsopermit of the attachment of the parts quickly without'the use of ascrew-driver or other tool.

These andother objects are attained by means of the constructionillustrated in the accompanying drawings, in which- Figure 1 is anenlarged perspective view of a portion of the lens-frame of an eyeglass.Fig. 2 is a perspective view of the spring bridge-piece. Fig. 3 is aperspective view of the nose-piece; and Fig. 4 is a sectional view takenthrough the bridge-piece, the nosepiece, and the integral stud-post.

Referring to the drawings for a more particular description of myinvention, the numeral 1 designates the lens-frame of an eyeglass, and 2is the stud-post, which may be formed in one piece with the frame. orwhich may be secured thereto in any suitable manner. The stud-post isprovided with a pair of inwardly-extending jaws 3, and centrallydisposedbetween the jaws is a stud 4. The bridge-piece 5 is provided at itsterminal ends with a round aperture 6 and an elongated.

slot 7. The aperture 6 is adapted to engage the stud 4 in the post. Theshank 8 of the nose-piece is provided with a spring-tongue 9, cut fromthe shank and bent outwardl therefrom to engage theslot 7 in the shan ofthe bridge-piece.

The manner of connecting and disconnecting the bridge-piece and nOseiece may be described as follows: The aperture 6 in the shank of thebridge-piece is engaged with the stud 4 between the jaws 3. thenose-piece is then inserted between the jaws 3 and pushed upward untilthe springtongue 9 snaps into the slot 7 in the shank of thebridge-piece, the nose-piece then being drawn outward until the tongue 9engages the lower wall of the slot 7, thus holding the parts firmly inposition. The stud 4 projects sufiiciently to engage the aperture 6 inthe shank of the bridge-piece and lies substantially flush with thesurface of said shank or sufficiently so as to not interfere with theadjustment of the shank of the nose-piece between the jaws 3.

From the foregoing it will be obvious that the bridge-piece andnose-pieces of an eyeglass made in accordance with my invention can beconnected and disconnected without the use of a screw-driver or othertool and that the parts can be readily assembled'by hand and whenconnected will be firmly and reliably assembled.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principleorsacrificing any of the advantages of this invention.

Having thus described my invention, what The shank 8 of I claim as new,and desire to secure by Letters Patent, is

An eyeglass comprising a stud-post provided with inwardly-extending jawsand a centrally-disposed stud between said jaws, a bridge-piece providedwith an apertureand a slot below said aperture, and a nose-piece havinga spring-tongue cut from its shank and projecting at one side thereof,said nosepiece and bridge-piece being secured between the jaws of thestud-post by means of the stud entering the aperture in the bridge-pieceand the tongue on the nose-piece being sprung into the slot in thebridge-piece, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- HGSSGS.
